The main reason I ordered an Avalon was to have my vote in the BTC system, it's not just about ROI in BTC. I don't know if that matters to any of you, but it's something to keep in mind. All of your BTC are subject to the whims of the people running the network with their hash power. I had a large stake in that with GPUs until recently, and I don't intend to let it go. No refund for me, I'll take it when I get it (hopefully sooner rather than later of course).
